I got a junkyard ECU today out of a 90-92 Toyota 4Runner, for my 94. I opened them up and the junkyard one is a little different than the one already in my 94. I understand there will be changes between years and some of the part numbers wont match up but there both automatic, 4x4, 3VZE powered trucks. It seems to run just as it did before with the 94 ECU, so i was just wondering if there was a problem out there with interchanging ECU's that i didnt find while researching, such as wiring pin-out for the sensors and what not

The ECU out of my 94 worked fine also but kept throwing codes in the end resulted in a faulty ECU, not that millage should matter at all my truck has 163k on it VS the 223k that was on the junkyard ECU.

Anyway, all input on the subject would be greatly appreciated, thanks in advance

 

no one?

 

Search.. I've posted a list on here a few times that shows variety of ECUs.

 

i did search and the back posts dont really answer anything

 

the junkyard one also is 89661-35441 and the one in the truck is 89661-3d020 and i didnt see either on your lists in back threads. i found someone else using 35441, being there both automatic ECU's i guess there cant be a problem

 

well if anyones wondering, they are compatible with each other, all problems from my fried ECU are gone
